Dappy has had a hashtag symbol tattooed on his face.

The rapper posted a photograph of his new inking on Twitter, whilst at the same time revealing the unusual motivation behind the design.

The 26-year-old star, who already had a number of tattoos, including designs on his head and neck, captioned the photograph: ''By the way, the reason I got a # Tatted on my FACE was simply 2 make sure IT stays trending 4 ever. (sic)''

The photograph was re-tweeted more than 400 times and while some followers praised his decision to have the hashtag sign tattooed to his face, others branded him an ''idiot''.

Former N-Dubz star Dappy's trip to the tattoo studio comes after Twitter bosses revealed last month that they are planning to scrap the sign altogether.

Twitter's head of news, Vivian Schiller, called the symbol ''arcane'' and explained: ''There's a lot of creative thinking going on around how to make Twitter more and more intuitive. Watch this space.''

One follower tweeted Dappy, saying: ''Some bad news dappy, twitter are planning to remove the # tag lol (sic).''

While another fan thought the inking suited the star and wrote: ''Suppose there ain't many people who could pull it off but looks awesome lad. (sic)''
